Title: Winding of friction elements
Inventor: JONES TERFEL
IPC: B29C70/38
Filed: 1992-08-22
Abstract: An annular preform 18 for a clutch friction facing is wound from an impregnated filament 11 on a rotating face plate 17 and held and consolidated by a non-rotating tailstock pressure plate 20 movable by ram 21 and through which the filament passes to the face plate. Plate 20 carries pressing rollers 29. To ensure the leading end of the filament is properly attached to the rotating plate and laid down in the proper (lobed) pattern, the rotation rate is relatively slow and tailstock pressure relatively high. Thereafter, and with the filament properly anchored, the rotation rate is increased significantly to shorten the overall winding time and/or the tailstock pressure is reduced to prevent disturbance or damage to filament layers deposited on other filament layers. A sequence of rotation rates and pressures may be matched to different patterns of winding in the same preform. The pressure plate may be temperature controlled to optimise filament adhesion characteristics. <IMAGE>

Title: Circuit for controlling discharge of a battery prior to charging
Inventor: SATO SYOJIRO
IPC: H02J7/04
Filed: 1992-09-09
Abstract: The battery 11 is discharged in response to its loading into a discharger which has a control I.C. 12 powered by the battery 11, circuit 12 including a discharge control flip-flop (22), (Fig 2), responsive to a battery voltage comparator to terminate the discharge when the battery voltage falls below a reference level, an undervoltage lock-out circuit (24) which resets logic elements in circuit 12 if the voltage Vcc at battery terminal 8 is below a threshold VTH indicative of abnormal conditions, and a monostable multivibrator timer (21) which operates in association with the lock-out circuit (24) to delay response of the control flip-flop (22) to the battery voltage comparator, thereby preventing false discrimination of the discharged or non-discharged state of the battery such as may be caused by contact bounce/chattering on initial loading of the battery or by influence of the self-heating and temperature characteristics of the battery. Circuit 12 controls a transistor Q1 to start constant current discharge of battery 11 through a resistor R1 after the delay period, the discharging state being indicated by LED 13. A switch SW1 may be operated to terminate discharge. <IMAGE>
Patent GB-922776-A (GB)
Abstract: 922,776. Cash registers. C. & A. BRENNINKMEYER G.m.b.H. April 28, 1961 [Dec. 15, 1960], No. 15529/61. Class 106 (1). Ticket-cutting and stacking apparatus is characterized by control means disposed in a ticket-insertion slot and adapted for initiating an automatically performed sequence of operations which results in the severing of a stub from an inserted ticket, the removal of the latter initiating an automatically performed sequence of operations resulting in the stacking of the stub in a storage container. The insertion of a ticket 10 in a slot 14 of a cash register, causes a flap 16 to operate a microswitch contact and illuminate a lamp 18. When the ticket is in the correct position, light from this lamp passes through apertures 20, 19, 22, on to a photo diode 23, thus energizing a relay 27, Fig. 10 (not shown). The ticket extends through a slot 15 in the cover 13 of a collecting drawer 8, and its lower edge 29 engages two feelers 30, thereby operating a microswitch 31 and energizing a magnet which, by means of two pins 33, secures the ticket against a guide blade 21 in the cutting position. Simultaneously, a relay is energized which causes a first motor 28, Fig. 1 (not shown), to execute an angular movement. This moves a cutting plate 34 against a stationary counter cutter 35 and produces a profiled cut, Fig. 4 (not shown), until the motor is disconnected by a finger which is fixed to the plate 34, engaging a stationary microswitch. An arm 41, also secured to the cutter 34, pushes a carriage 43, to the rear of drawer 8, in a track 42, until the ratchet tooth 45 of a latch 44 engages the top of a fixed wall 46. This withdraws the feelers 30 from the drawer 8 so that the stub of the ticket can drop into its stacking position. Withdrawing the remainder of the ticket switches on the motor 28 once more to execute a return movement. The cutter 34 withdraws until the attached finger contacts another microswitch which disconnects the first motor and, via a relay, starts a second motor which moves a set of stacking pins 60 into apertures 61 on the rear portion 62 of the drawer 8, pushing forward a spring-urged slide member 77 and thus stacking the severed ticket stub at 79. As the stacking pins advance, a plate 106 attached to them, releases a latch 44, thus allowing the spring-urged carriage 43 to return. Means are provided for counting the number of cutting operations and for indicating when the stacking drawer, which may be part of the cash drawer, is full. The lid 13 of the drawer 8 is normally locked in position and a spring-biased slide 73 automatically closes the slot 15 when the drawer is removed from the housing.

Title: Method and apparatus for controlling condensation of gaseous hydrocarbon stream
Inventor: DEVERS BARNARD JAMES
IPC: F25J1/02
Filed: 1997-10-14
Abstract: In a cryogenic condensation scheme used for benzene removal in a process for liquefying natural gas, two series connected separation columns (10, 12) are provided with a feedstream (44) precooled in a heat exchanger (16) to a temperature that will at least condense the benzene component. In the first column (50), benzene is absorbed and vapor/liquid is separated with the liquid passed to the second column (60). The second column (60) provides an overhead vapor stream (68) conserved for processing to LNG, and a bottom stream comprising NGL. The cooling for condensation of gaseous feed in the heat exchanger is controlled by automatically manipulating bypass flow (38) around the heat exchanger responsive to measured vapor flow (80) from the second separation column. Accordingly, the amount of liquid (36) condensed is responsive to the flow rate of vapor withdrawn overhead from the second separation column.
